title: Unusual features of control region and a novel NADH 6 genes in mitochondrial genome of the finespot goby, Chaeturichthys stigmatias (Perciformes, Gobiidae).
abstract: In this article, we determined the complete mitogenome of finespot goby Chaeturichthys stigmatias with emphasis on the arranged gene order and gene feature with published Gobiidae species. The C. stigmatias mtDNA was 18,562 bp in length (56.94% AT), and comprised 37 genes (13 protein genes, 2 rRNAs and 22 tRNAs) that was typical for mitochondrial genome of Gobiidae species. Unusually, the NADH 6 gene was very large in length compared with other Gobiidae species. Mitogenome of C. stigmatias had a long putative control region with high AT content (71.28%). Within this sequence, we determined repeat regions, the termination-associated sequence and the conserved sequence block for this region. The origin of L-strand replication in C. stigmatias was located in a cluster of five tRNA genes (WANCY). The conserved motif (5'-GCCGG-3') was also determined at the base of the stem in the tRNA-Cys gene. This study will provide a better understanding of Gobiidae mitogenomes and offer useful information for future studies concerning Gobiidae mitogenome evolution.
